Transport and Dispatch Considerations
- International express services are commonly used for documents, samples, and compact urgent shipments; confirm that the carrier serves the exact street address.
- Air freight can suit higher-value or time-sensitive commercial cargo, with customs clearance and final-mile delivery coordinated through the selected forwarder or carrier.
- Ocean freight, including LCL or FCL, generally requires inland transport after arrival at a United States port or intermodal gateway. The routing and handoff depend on the shipment plan.
- For commercial goods, provide a consistent commercial invoice with an accurate goods description, value, quantity, country of origin, and applicable tariff classification. Documents and merchandise should not be declared interchangeably.
- Provide a working consignee telephone number and confirm the importer-of-record details and any shipment-specific customs identifiers with the broker or carrier. U.S. import requirements depend on the goods and transaction.
- Check delivery constraints before using a post office box: some courier or freight services require a physical street address, and accessorial or remote-area conditions must be confirmed with the carrier.
